    Description

      The unit test CompactionStrategyManagerTest.testAutomaticUpgradeConcurrency fails occasionally at least in trunk:

      unit.framework.AssertionFailedError: expected:<1> but was:<0>
	at org.apache.cassandra.db.compaction.CompactionStrategyManagerTest.testAutomaticUpgradeConcurrency(CompactionStrategyManagerTest.java:227)
	at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method)

      The failure can be reproduced with:

      .circleci/generate.sh -p \
  -e REPEATED_UTESTS=org.apache.cassandra.db.compaction.CompactionStrategyManagerTest \
  -e REPEATED_UTESTS_COUNT=1000

      I have only tested trunk. I haven't seen it on Butler.

      Observed flakiness is ~0.2% for all jobs except for tries, which ramps up to ~2.5%.
